如何使用req.params.ids删除多个数据(多个ids)

const express = require('express');
const app = express();
const port = 3000;

// 假设我们有一个items数组来模拟数据库中的数据
let items = [
  { id: 1, name: 'Item 1' },
  { id: 2, name: 'Item 2' },
  { id: 3, name: 'Item 3' },
  // ...更多项
];

app.delete('/items/:ids', (req, res) => {
  // 从URL参数中获取ID字符串并分割成数组
  const idsToDelete = req.params.ids.split(',');

  // 过滤掉要删除的项
  items = items.filter(item => !idsToDelete.includes(item.id));

  res.status(200).json({ message: 'Items deleted successfully', remainingItems: items });
});

app.listen(port, () => {
  console.log(`Server running at http://localhost:${port}/`);
});

app.delete('/items/:ids', (req, res) => {
  const idsToDelete = req.params.ids.split(',').map(id => parseInt(id, 10));

  // 验证所有ID是否有效
  if (idsToDelete.some(isNaN)) {
    return res.status(400).json({ error: 'Invalid ID format' });
  }

  items = items.filter(item => !idsToDelete.includes(item.id));

  res.status(200).json({ message: 'Items deleted successfully', remainingItems: items });
});
